I also spend a good deal of time combing through charts and it IS infuriating! I got some reports from another hospital one time, and except for the envelope in which it came, there was no way to tell where care was being given, just from the notes/reports alone. No letterhead, logo, institution name or anything. There doesn't seem to be a regulation, rule, or best practices scheme for what information should be included in every note, report, chart, result. IMHO, every page printed out should have the patient's name, DOB, MRN, page numbers (the lack of which has caused me a headache or two), and a clear designation of where this note came from: institution, department, service, attending physician, and type of document (H&P, progress note, lab result, etc).
